[0028] Among them, the housing 11 is the main frame of the entire left coupler mechanism, responsible for providing structural support and protecting the internal key components from the external environment and vibration. It carries the installation and fixation of other components. The interlocking device 12 is located in the middle of the housing 11 and plays a connecting and locking role. It includes a complex mechanical system that can ensure that the coupler is firmly locked when connected to prevent accidental unlocking.

The locking block 122 is connected to the outer contour of the rotating column 121 and is connected to the rotating column 121 by rotation. The main function of the locking block is to ensure the firm and safe locking of the coupler connection through the movement of the mechanical structure.

[0030] The pressure rod ejection mechanism 18 includes a connecting block 181, an ejection head 182 is inserted into the lower end of the connecting block 181, and a compression spring 183 is arranged between the lower end of the ejection head 182 and the connecting block 181.

The ejection head 182 is a component inserted into the lower end of the connecting block 181, and is designed to push or eject related components when necessary, such as the operation of the pressure rod 15 or other connecting devices.

It is usually fixed to the inner wall of the upper end of the shell 11 to ensure the position and stability of the mechanism. The reset head 192 is inserted on the left side of the base 191, and is designed to be connected to the operating part of the pressure rod 15. The main function of the reset head 192 is to push the pressure rod back to the initial position after use, ensuring that the interlocking device 12 can re-lock the operation. The reset spring 193 is fixed at the tail end of the reset head 192, and is designed to provide elastic support for the pressure rod reset. After the pressure rod is pushed out, the reset spring 193 will apply an appropriate reverse force to quickly and accurately reset the pressure rod to the original position, ready for the next connection operation.

[0034] Working principle:

[0035] 1. Position sensors detect coupler position: In the design of the device, the left and right coupler mechanisms are each equipped with position sensors 3, which are located at the four corners of the coupler. Their function is to detect the precise position and alignment of the left and right couplers when connected. The position sensors can determine whether the couplers are properly attached and in the correct position by measuring the position or distance of specific points.

[0036] 2. Pressure sensors detect the engagement state: Pressure sensors 4 are installed on the sides of the left and right coupler mechanisms. These sensors are used to detect the pressure applied by the pressure rod 15 during the connection. The design of the pressure rod ejection mechanism 18 and the pressure rod reset mechanism 19 ensures that a certain amount of pressure is applied to the pressure sensor when the couplers are fully docked.

[0037] When the coupler is correctly engaged, the push rod ejection mechanism 18 will apply sufficient pressure to the pressure sensor through the design of its ejection head 182 and compression spring 183. The pressure sensor can measure this pressure to confirm that the coupler is correctly and tightly engaged.

[0038] 3. Functions of interlocking device and other mechanical parts: The interlocking device 12 ensures that the coupler can be firmly locked when it is fully docked through its design, such as the rotating column 121 and the locking block 122, to prevent accidental unlocking or loosening. The structure of the locking rod 14 and the tension spring 17 ensures the stability of the lock, while allowing a smooth unlocking operation when necessary.

[0039] These components and sensors work together to ensure that the detection device at the high-speed rail connection can accurately and reliably detect and confirm the correct connection status of the left and right couplers. Through the data of the position sensor and pressure sensor, the system can monitor and feedback the quality and safety of the coupler connection in real time to ensure the safe operation of the high-speed rail train.
